TPS65313-EVM Typical Plots
This section provides plots for efficiency, start up, power down, ripple voltage, load transient response,
and stability. All the plots were taken with 13-V at the VIN pin, one EVM, room temperature, with the
BUCK1 output connected as the supply for the BUCK2 regulator and BOOST converter.

Efficiency Plots
The total current in to the VIN, AVIN, and VIN_SAFE pins was
considered for this plot with the EXTSUP supply connected to the
BOOST converter.
